If you have a disc herniation without motor weakness, I would try the epidural steroid first. If you have motor weakness, I would go with the surgery.
Recurrence of disc herniation is about 10% with or without surgery. The disc will not regrow and the space will remain empty. However, the disc will narrow to fill in the empty space like letting some air out of a car tire.
An epidural injection might allow you to ski in two months. A surgery if performed today will also allow you to ski in 2 months.
